Tehnical suport PLC Low Cycle time

[Alex_Hluscu]

Good day,

My name It’s Alex, automation engineer for Contrail Machinery, manufacturer of Railway welding equipment.

We are looking for some thenical support to find and choose best product for our application.

Right now we are using Allen Bradley PLC, but we are looking for something faster refering to PLC Cycle time and fast communication with pheripherals Points.

Allen Bradley 5069 PLC cycle time it’s above 1 ms, and ethernet communication with  pheripherals are affected by 2 ms communication delay + PLC cycle time.

We are looking for speeds below 1 ms cycle time and fast way for communication with  pheripherals.

Please let us know if you are open for detailed further discussion.

If you are looking for communication with low latency, perhaps you want to consider non-Ethernet-based options. See Table 1 in Instrument Bus Performance – Making Sense of Competing Bus Technologies for Instrument Control

Thank you, very much, make sense for me and I understand, I had a look for GPIB type of communication between PLC Master and PLC Point.
